Title: Force feedback type hydraulic pressure control valve
Inventor: MITO AKIO
IPC: F15B13/043
Filed: 1980-03-04
Abstract: PURPOSE: To obtain high pressure gain, by forming the length between the insides of lands at both sides of a pilot spool slightly larger than the thickness of a valve main body and equalizing fluidic resistances in left and right opening parts when the pilot spool is in a neutral position.  
     CONSTITUTION: Inner walls of controlling lands 44a and 44b of a pilot spool 44 are processed in precision work finish to form the axial length D slightly larger than the thickness C of a main body 42. Then the pilot spool 44 is formed at its neutral position in such a manner that its both side opening lengths are equal to be X 1 =X 2 . When a coil 25b is excited to press a control pin 28, the pilot spool 44 is moved leftward to obtain a relation of X 1 <X 2 , then pressure in a pressure chamber 4 becomes higher than in a pressure chamber 3 to press a main spool 2 rightward and perform force feedback operation. In this way, because of both obtaining higher pressure gain and eliminating occurrence of a fluidic ankylosis phenomenon by designing the shape of a spool or land, no dither or filter is required.

The electrode 14 consisting essentially of the Ti and the electrode 15 consisting essentially of the Al are arranged to face each other in front of this substrate. These electrodes are made movable forward and backward by respective reciprocating mechanisms 16, 17. The pressure in the chamber 20 communicating with the chamber 12 is reduced by a pump 21 and the electricity is discharged between a pair of the Ti electrodes 22 and 22 to coat the inside surface 23 of the chamber 20 with the Ti. The remaining trace oxygen is expelled. Next, arcs are discharged with a power source 18 by attaching and detaching the electrodes 14, 15 and the Ti and Al evaporated from both electrodes form the TiAl 3  layer of 0.005 to 0.1 inch thickness on the surface of the polyacrylate model 10. The TiAl 3  layer is taken out of the model 10 and is heat treated, by which the high-density molding is obtd.

IPC: H01L27/148
Filed: 1981-02-26
Abstract: PURPOSE:To suppress noises by providing an electrode between an input electrode and a transfer electrode, by applying a voltage whose frequency is equal to a transfer frequency and which is synchronized with a transfer voltage, and weighting the inflow charge. CONSTITUTION:The electrode 5 is provided between an input gate 3 and the transfer electrode 4. The weighting voltage whose frequency is equal to the transfer frequency fc of the CCD, and which is synchronized with a transfer waveform (e) and varies in the similar way with a sine wave or Gauss distribution wave (f) whose waveform varies smoothly. In this constitution, since a  potential plane 25 directly under the electrode 5 fluctuates up and down in a  time domain, the current flowing in the direction shown by an arrow (h) is weighted, and the spectrum component of 2fc of or more is remarkably decreased. Since the noise component in a high frequency region is remarkably decreased accordingly, the noises introduced in the region of 0-fc/2 is remark  ably decreased even though reflection occurs. Therefore the S/N ratio of the  CCD is drastically improved.
